To all whom t may con/cern:v

Beit known that I, PRESLEY ALPHEUS GoN- GOUR, a citizen of the United States, residing at Enloe, in the county of Delta and State of Texas, have invented a new and useful Adjustable Table, of which the following is a speciiication. A

The invention relates to improvements in adjustable tables. l

The object of the present invention is to improve the construction of adjustable tables and to provide a simple, inexpensive, and efiicient one adapted to be readily arranged at the desired elevation and capable of being readily adj usted to form an ordinary table, an extension-table, artists easel, or a desk.

Another object of the invention is to provide a table of this character in which the top may be arranged to form a box or receptacle to retain its contents on it.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of an adjustable table constructed in accordance with this invention, the top of the table being arranged in a horizontal position. Fig. 2 is a vertical sectional view of the same, the parts being arranged to form an extension-table and showing in dotted lines the top arranged to form an artists easel. Fig. 3 is a vertical sectional view taken at right angles to Fig. 2. Fig. 4 is a detail sectionall view illustrating the manner of adjustably mounting the shelf upon the main section or leaf of the table. Fig. 5 is an enlarged detail sectional view illustrating the arrangement of the hinges. Fig. 6 is a plan view of one of the hinges.

Like numerals of reference designate corresponding parts in all the iigures of the drawings.

l designates a stand provided with a pair of vertical ears or pieces 2, extending upward and receiving between them an adjustable connecting-plate 3, which is similarly connected with the top of the table. The top of the table, which is composed of a main leaf or section 4 and a hinged leaf or section 5, is

provided with a pair of depending ears or pieces 6, connected with and extending from the lower face of the main leaf or section 4 of the top and receiving the upper end of the connecting-plate 3. The ears or pieces 6, which are spaced apart, are secured to the opposite faces of the cleat 7, which is fastened Vto and extends longitudinally of the top of the table.

The stand l, which may be constructed in any desired manner, is preferably composed of crossed bars or pieces 8, centrally secured together and arranged to form legs, as clearly shown in Fig. l of the accompanying drawings, and the perforated ears or pieces 2 have their lower portions slotted or bifurcated and arranged at opposite sides of one of the crossed bars or pieces 8 and receiving the other crossed baror piece 8 in their slots or bifurcations.

The connecting-plate 3, which is substantially diamond-shaped, is oppositely tapered, as shown, and is provided with reversely-arranged upper and lower longitudinal slots 9 and l0, receiving the upper and lower pivots ll and l2, which connect the plate with the stand and the top of the table.n These pivots, which pass through perforations of the par allel ears 2 and 6, are preferably in the form of Screws and are provided with suitable nuts 13 and 14, whereby the perforated ears are caused to clamp the coupling-'plate 3 and secure the table at any desired adjustment. The nuts, which are provided with suitable handles or other means whereby they may be readily operated, engage one of the perforated ears of each pair, and the screws or bolts which constitute the pivots are provided with transverselyelongated heads ll and 12a, having their terminals extended inward and embracingthe adjacentears. Theinwardly-bent terminals of the heads engage the edges of the adjacent ears and prevent the pivots from rotating when the nuts are being operated. The slots, which are located adjacent to the opposite edges of the plate 3, extend inward from the terminals thereof and are provided at their inner ends with angularly-disposed extensions or seats l5 and 16, adapted to receive the pivots when the latter are arranged at the inner extremities of the slots. The

IOO

plate 3 may be raised and lowered and swung in either direction and can be adjusted to bring the table-top at either side of the center of the stand to arrange it in the most convenient position for use, and when the hinged leaf 5 of the top of the table is extended, as illustrated in Fig. 2 of the drawings, the top of the plate may be arranged to project over a bed to bring its contents within easy reach 0f an invalid without subjecting him to any pressure.

The top of the table may be used for all the purposes to which an ordinary table can be put, and when the leaves are extended theyv may be tilted to an inclined position, as illustrated in dotted lines in Fig. 2 of the drawings, to forni an artists easel, and they can be arranged to form a childs desk or a support for a blackboard or the like.

The main leaf is provided at one end with a shelf 16, adapted to be used when the parts are arranged to form an easel and secured between the adjacent edge of the top of the table and acleat or stop 17, which is connected with the table by pins 18. The pins 1S pass through transverse slots 19 of the shelf, and

in order to enable the latter to be adjusted to project it the desired extent above the top of the table the transverse slots are provided with longitudinal branches 20, extending in the same direction and adapted to receive the pins 18. The shelf is capable of being reciprocated longitudinally to carry the pins into and out of the longitudinal branches 20, and the transverse slots permit the shelf to be depressed and elevated to bring any one of the longitudinal branches opposite the pins 18. The longitudinal branches 20, which may be of any desired number, are shown arranged at the ends and center of the transverse slots 19.

The hinged leaf 5, which is provided with sides 21, is connected with the adjacent edge of the main section or leaf @t by double or compound hinges 22, adapted to permit the leaf 5 to swing upward and downward below a horizontal position to fold upon the main leaf, as

illustrated in Fig. 1, or to swing down out'of the Way. The double or compound hinges are composed of three leaves, the outer leaves being secured, respectively, to the sections of the top of the table and connected to the ends of the central leaf by hinged joints. The central leaf is provided at each end with eyes, and a pair of pintles is employed for each hinge. One of the end leaves of the double hinge is secured to the upper face of one of the sections of the table-top, and the other end leaf of such hinge is attached'to the lower face of the other section of the table-top, and the hinges are reversely arranged, whereby the sections of the table-top are held closely together at their adjacent edges and are at the same time permitted to swing in both directions. The sides 21 are rigid with the leaf or section 5, and when the latter is arranged as illustrated in Fig. 1 of the drawings the said sides cooperate with lthe shelf 1G to form a box for preventing the contents of the table from falling o the top. The hinged end of the leaf or section 5 is provided with a piece 23, completing the sides of the box, and centrally pivoted by means of a pin 24, whereby it is adapt.

ed to be turned at right angles, as illustrated in Fig. 2, to form a locking-bar to retain the link or section 5 in a horizontal position.

The invention has the following advantages: The table, which is simple and comparatively inexpensive in construction, is capable of ready ad j ustm ent to raise and lower its top to bring the same to the desired elevation, and it may be arranged to form an extension-table, an artists easel, or a desk." The slotted connecting-plate is adapted to swing horizontally and can be arranged for vertical or horizontal adjustment, so that the table-top maybe projected over a bed to bring its contents within convenient reach of an invalid, and when the table is adjusted in any of its various positions it is securely retained in such adjustment by the clamping devices carried by the pivots. The main section or leaf of the top of the table is provided with an adjustable shelf, which is adapted to be raised and lowered to project the desired distance above the top of the table, and the hinged leaf has sides which cooperate with the shelf to form a basket or box for retain-V ing the contents of the table on the same. The leaf or section 5 is adapted to swing upward and downward independent of the main leaf or section, and the transverse` end piece 23 is adapted to be turned at right angles to its normal position to form a locking-bar for holding the leaf or section 5 in an extended position.

Changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacriicing any of the advantages of this invention.
